BACKGROUND

1. Field of Inventions

The present inventions relate generally to apparatus and methods for charging the rechargeable batteries (and/or other rechargeable power sources) in implanted medical devices.

2. Description of the Related Art

A variety of power consuming medical devices may be implanted into a patient.

Examples of such implantable medical devices include, but are not limited to, microstimulators (e.g. occipital nerve stimulators, vagus nerve stimulators, and stimulators that may be positioned at various locations to treat rheumatoid arthritis), implantable pulse generators, drug infusion pumps, speech processors, pacemakers and defibrillators. In addition to their therapeutic and/or diagnostic components, the implantable medical devices include rechargeable power sources such as rechargeable batteries, capacitors, and combinations thereof. The length of time that an implantable medical device can operate between chargings of the rechargeable power source varies from device to device. For example, pacemaker batteries may only need to be recharged every few years, while microstimulators (e.g. an occipital nerve stimulator) may need to be recharged several times a day.

The present inventors have determined that conventional methods and apparatus for charging the rechargeable power sources in implanted medical devices are susceptible to improvement. For example, the present inventors have determined that conventional methods and apparatus for charging the rechargeable power sources can involve the use of large and bulky chargers that are difficult to incorporate into daily life. The present inventors have also determined that it can be difficult to maintain the proper position of conventional chargers on the body relative to the implanted medical device.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The following is a detailed description of the best presently known modes of carrying out the inventions. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the inventions. The detailed description is organized as follows:

I. Overview

II. Exemplary Charging Appliances That May Be Associated With Wearable Devices

III. Charging Appliances That May Be Associated With Non-Wearable Devices

The section titles and overall organization of the present detailed description are for the purpose of convenience only and are not intended to limit the present inventions.

I. Overview

As illustrated in FIG. 1A, a medical device 10, having an external housing 12, an internal inductor 14 (e.g. a conductive coil and a core of air or a ferromagnetic material), a rechargeable power source 16, and power consuming apparatus (e.g. a controller 18 and electrodes or other therapeutic devices 20 a and 20 b), may be implanted in a patient P. Examples of medical devices that may be implanted into a patient include, but are not limited to, occipital nerve stimulators, such as that illustrated in U.S. Pat. No. 6,735,474, other microstimulators, implantable pulse generators, drug infusion pumps, speech processors, pacemakers and defibrillators. The power source 16 in the medical device 10 may be charged with a charging appliance 22.

The exemplary charging appliance 22, all or part of which may be positioned on or near the patient in close proximity to the implanted medical device 10, includes one or more inductors 24 (herein after “inductor”), inductor related circuitry 25 (e.g. tuning capacitors, switches and temperature sensors), a power supply 26 (e.g. a primary battery, a replenishable or rechargeable battery such as a lithium ion battery, an electrolytic capacitor, a super- or ultra-capacitor, or some other power supply), a controller 28 and a user interface 30. In those instances where the power supply is replenishable or rechargeable, apparatus for replenishing or recharging the power source (e.g., an RF link, an optical link, a thermal link, or other energy-coupling link, may be provided. The user interface 30 may consist of any suitable instrumentality including, for example, one or more buttons, a touch screen, one or more LEDs (or other visible indicators), and a buzzer (or other sound emitting device) or a vibrating mechanism. The power source 16 in the implanted medical device 10 may be charged by transferring power from the power supply 26 to the implanted power source 16 by way of the inductors 14 and 24.

As is described in greater detail below, the charging appliance 22 (or at least a portion thereof) may be carried by, part of, secured to and/or otherwise related to an apparatus that is associated with the patient's everyday life. For example, and referring to FIG. 1A, the inductor 24 and inductor related circuitry 25 may be incorporated into a device 32 that is carried by, part of, or secured to an apparatus that is associated with the patient's everyday life, while the power supply 26, controller 28, and user interface 30 will be included in a remote housing 34 that is connected to the inductor 24 by a cable 36 with an output line and a return line. The cable connection may, however, be replaced by wireless connection in the embodiment illustrated in FIGS. 1A and 1 n each of the embodiments described below that includes a cable connection. Alternatively, in the exemplary charging appliance 22 a illustrated in FIG. 1B, the inductor 24, inductor related circuitry 25, power supply 26, controller 28, and user interface 30 may be part of the same device 32 a, which has a single common housing and may be carried by, part of, or secured to an apparatus that is associated with the patient's everyday life.

The actual position of the inductor will depend on the location of the implanted medical device. An inductor that is positioned adjacent to the back of the neck may be used, for example, to charge the power source in an occipital nerve stimulator or an implantable pulse generator (IPG) with one or more leads for trigeminal nerve stimulation or deep brain stimulation. An inductor that is positioned near the front or side portion of the neck may be used, for example, to charge the power source in a vagus nerve stimulator. An inductor that is positioned on or behind the ear may be used, for example, to charge the power source in an IPG with one or more leads (e.g. for trigeminal nerve stimulation) implanted behind ear or to charge the power source in a cochlear implant, while an inductor that is positioned on or in front of the ear may be used, for example, to charge the power source in an auriculotemporal nerve stimulator. Inductors that are positioned on or adjacent to the chin or forehead may be used, for example, to charge the power source in a trigeminal nerve stimulator. Inductors that are positioned at various locations around the waist may be used, for example, to charge the power source in an ilioinguinal nerve stimulator or the power source in an IPG that is mounted at or near buttocks with leads that may be used in any of a wide variety of stimulation therapies. An inductor that is positioned just below the chest may be used, for example, to charge the power source in an intercostal nerve stimulator or the power source in a phrenic nerve stimulator. Inductors that are positioned on or adjacent to other portions of the torso (e.g. beneath the axilla, on the upper chest near the shoulder, or in the mid-back area) may be used, for example, to charge the power source in an IPG with one or more leads for spinal cord stimulation, occipital nerve stimulation, deep brain stimulation, or to charge the power source in a stimulator implanted to treat post thoracotomy pain. Inductors that are positioned on or adjacent to joints (e.g. the knee or the wrist) may be used, for example, to charge the power sources in stimulators that treat rheumatoid arthritis. An inductor that is positioned on or adjacent to the pelvic region may be used, for example, to charge the power source in a pudendal nerve stimulator.

It should also be noted that a wide variety of inductors 24 may be employed. By way of example, the inductor 24 a illustrated in FIG. 2A includes a coil 38 and a ferromagnetic core 40, while the inductor 24 b illustrated in FIG. 2B includes the coil 38 and an air core. Turning to FIG. 2C, the inductor 24 c includes a relatively flat, tightly wound coil 42 and a ferromagnetic core 44. In each instance, the dimensions of the inductor may depend on the dimensions of the underlying charging appliance. For example, the inductor 24 c may have a relatively small diameter in some of the embodiments described below and a relatively large diameter in others.

II. Charging Appliances that May be Associated with Wearable Devices

Wearable devices are one example of apparatus that charging appliances may be carried by, part of, secured to and/or otherwise associated with. As used herein, a “wearable device” refers to all clothing (or “garments”), clothing clasps, costumes, harnesses, jewelry, piercings, hats and other head coverings, eye glasses, uniforms, sporting goods that are carried by the body or are otherwise worn, prosthetics, footwear and shoe inserts, protective gear, bags (e.g. a backpack or purse), externally worn medical devices and externally worn non-medical electronic devices (e.g. headphones). Regardless of the type of wearable device, the wearable device and charging appliance will cooperatively position the associated inductor in close proximity to the implanted medical device to facilitate charging in, for example, the manner described above with reference to FIG. 1A.

As illustrated in FIGS. 3-6, an exemplary charging appliance 100 includes a magnetic clasp 102 that carries one or more inductors and inductor related circuitry (e.g. inductor 24 c and related circuitry 25) and a remote housing 104 that carries the power supply and control apparatus (e.g. the power supply 26, controller 28 and user interface 30). A cable 106 connects the inductor and inductor related circuitry carried by the magnetic clasp 102 to the power supply and control apparatus carried by the remote housing 104. The cable 106 may be replaced by wireless connection in the embodiment illustrated in FIGS. 3-6 and in each of the embodiments described below that includes a cable connection. The magnetic clasp 102 may be secured to a shirt or blouse collar 108, any other garment or portion thereof, or any other wearable device, while the remote housing 104 includes a clip 110 that allows the remote housing to be mounted on, for example, a belt or other article of clothing.

The exemplary magnetic clasp 102 in the illustrated embodiment has a main portion 112, which includes the inductor 24 c and related circuitry 25, and a backing 114, which cooperates with the main portion to secure the magnetic clasp to the collar 108. The inductor 24 c and inductor related circuitry 25 may be molded into an epoxy, silicone, or urethane structure that is carried within a plastic case 116, thereby electrically insulating the main portion 112 from the wearer. Alternatively, the inductor 24 c and inductor related circuitry 25 may be carried within a polycarbonate case, that is itself coated with an insulating encapsulate such as silicone, rubber-like polymers, Teflon, and other plastics. Here too, the main portion 112 will be electrically insulated from the wearer. Turning to the backing, the exemplary backing 114 consists of a magnet 118 that is carried within a plastic housing 120 and attracted to the ferromagnetic core 44 of the inductor 24 c. The backing may, alternatively, consist solely of a magnet.

The magnetic clasp 102 may, in some implementations, be provided with apparatus that centers the main portion 112 relative to the backing 114. In the exemplary implementation illustrated in FIGS. 3-6, the main portion 112 includes a post 122 that is configured to pass through the associated article of clothing (i.e. is relatively sharp and thin) and the backing 114 includes an aperture 124 that is configured to receive the post. It should also be noted here that the main portion and the backing may, alternatively, be secured to one another through the use of non-magnetic instrumentalities, such as a snap, a button or thread, and that the backing 114 may be omitted and the main portion 112 secured to a garment or other wearable device with pins, hooks, buttons, clasps, buckles, clips, snaps or any other suitable mechanical fastener.

With respect to use, and as illustrated for example in FIG. 3, the main portion 112 of the exemplary magnetic clasp 102 may be placed on the inner surface of the collar 108, so that the inductor 24 c is close to the implanted medical device, while the backing 114 may be placed on the outer surface of the collar under the collar flap. As a result, the cable 106 will be located within the shirt or blouse and the charging appliance 100 will be completely, or almost completely depending on the location of the remote housing 104, out of sight. The wearer may then charge the power source of the implanted medical device by operating the user interface on the remote housing 104 (e.g. by pressing a button). The locations of the main portion 112 and backing 114 may also be reversed, so that the cable 106 will be located on the outside of the shirt or blouse, if so desired.

The charging appliance 100 may, of course, be used in combination with a wide variety of garments. By way of example, but not limitation, the charging appliance 100 may be used in combination with necktie 126 (FIG. 7), a coat 128 (FIG. 8), a scarf 130 (FIG. 9), a turtleneck collar 132 (FIG. 10) so as to position an inductor adjacent to a medical device that is implanted within the neck.

The charging appliance 100 may also be secured to caps, hats, helmets and other items that are typically worn on the head. One such hat, which is generally represented by reference numeral 134 in FIG. 11, includes a main portion 136, an inner rim 137 and a bill 138. The magnetic clasp 102 may be attached to any part of the main portion 136, the inner rim 137 (as shown), or the bill 138. Another exemplary hat is the safari hat 140 illustrated in FIG. 12, which includes a main portion 142, a bill (not shown), and flap 144 that shades the back of the neck. In addition to the main portion 142 and the bill, the magnetic clasp 102 may be attached to the flap 144 (as shown).

Turning to helmets, one example of a helmet to which the charging appliance 100 may be secured is the bicycle helmet 146 illustrated in FIG. 13, which includes a main portion 148 (e.g. a hard shell with an inner padded liner), a chin strap 150 and side straps 152 that are positioned in front of and behind the ear. The magnetic clasp 102 may be attached to the chin strap 150 (as shown), or to one of the side straps 152, or to the main portion 148. An exemplary equestrian helmet 154, which includes a main portion 156 (e.g. a hard shell with an inner padded liner), a chin strap 158 and side straps 160 that are positioned in front of and behind the ear, is illustrated in FIG. 14. Here too, the magnetic clasp 102 may be attached to the chin strap 158 or to one of the side straps 160 (as shown).

The charging appliance 100 may also be secured to belts and belt-like devices. Referring first to FIG. 15, the charging appliance 100 may be secured to a belt 162 that includes an elongate strap 164, which is sized to encircle the wearer's waist, and a mechanism to fasten one portion of the strap to another (e.g. the holes 166 and buckle 168). In the illustrated embodiment, the magnetic clasp 102 is secured to one portion of the elongate strap 164, while the clip 110 may be used to secure the remote housing 104 to another portion of the strap. A heart rate monitor 170 is one example of a belt-like device to which the charging appliance 100 may be secured. The exemplary heart rate monitor includes a sensor/display apparatus 172, an elongate strap 174 formed from an elastomeric material such as that sold under the trade name Neoprene, and a mechanism to fasten one portion of the strap to another such as hook and loop strips 176 and 178 (e.g. the fastener strips commonly sold under the trade name Velcro). Here, the magnetic clasp 102 is secured to the elongate strap 174. The heart rate monitor 170 will typically be positioned around the wearer's torso just below the chest. A similar constructed fetal monitor (not shown) is another example of a belt-like device to which the charging appliance 100 may be secured.

A joint brace, such as those commonly used to support the wrist, elbow, ankle or knee, is another example of a type of device to which the charging appliance 100 may be secured. Referring to FIG. 17, one specific example of a joint brace is the knee brace 180, which includes a cuff 182 formed from an elastomeric material such as that sold under the trade name Neoprene, an opening 184 for the wearer's patella, and adjustable straps 186.

The exemplary charging appliances illustrated in FIGS. 1A and 3-17 above and FIGS. 64-95 and 100 below include an inductor and inductor related circuitry which are located remotely from, and connected by a cable (or wireless connection) to, the user interface, controller and power supply. Other exemplary charging appliances, which are illustrated in FIG. 1B above and FIGS. 18-63 and 96-99 below include a charger with an inductor, inductor related circuitry, user interface, controller and power supply that are associated with a common housing or common overall device. The charger may be positioned adjacent to the implanted medical device, or part of the implanted medical device, in a variety of ways. For example, the charger may be secured to an article of clothing in such a manner that the article of clothing maintains the charger in the intended location.

The shoulder drape 450 may also be provided with a slip resistant bottom surface 460 (e.g. a rubber or textured surface) in order to reduce the likelihood that the charging appliance 448 will move relative to the user once shoulder drape 450 has been positioned in, for example, the manner illustrated in FIG. 53 with the charger adjacent to the implanted medical device.

As alluded to above, the fastening arrangement employed by the exemplary charging appliance 448 includes the magnets 212 and 458. A variety of other fastening arrangements may be employed to secure the ends of the shoulder drape to one another. By way of example, the charger 202 a, which does not include the additional magnet 212, may be employed. Here, the magnet 458 would cooperate with either the inductor magnet, or an additional magnet added to the shoulder drape 450 adjacent to the pocket 454. Other alternatives include, but are not limited to, snaps, buttons, and hook and loop fasteners.

Turning to FIGS. 54-58, the exemplary embodiments also include a wide variety of scarf-like charging appliances. Referring first to FIGS. 54-56, the exemplary charging appliance 462 includes the charger 202 a and a scarf 464 that is configured to mount the charger adjacent to the implanted medical device. The exemplary scarf 464 consists of an elongate flexible body 466, which has a pocket 468 with an opening 470 that is configured to receive the charger 202 a, and a fastening arrangement that maintains the scarf 464 in the desired orientation. In the illustrated embodiment, the fastening arrangement includes a button 472, a slot 474 and a plurality of button holes 476. The portion of the flexible body 466 with the button holes 476 may be inserted through the slot 474 and the button 472 secured to the desired button hole, as is illustrated in FIG. 55. To that end, the elongate flexible body has a relative wide portion 478, with which the pocket 468, button 472 and slot 474 are associated, and a relatively narrow portion 480 with which the button holes 476 are associated. Alternatively, the slot 474 may be omitted and the width of the elongate flexible body uniform from one end to another.

Another exemplary scarf-like charging appliance, which is generally represented by reference numeral 482 in FIG. 57, includes the charger 202 (not shown), a scarf 484 consisting of an elongate flexible body 486 with a pocket 488 having an opening that is configured to receive the charger, and a fastening arrangement that maintains the scarf 482 in the desired orientation.

Here, the fastening arrangement consists of the charger magnet 212 (or the inductor magnet) and a magnet 490, such as the exemplary decorative magnet, which is attracted to the magnet 212 and is not an integral part of the elongate flexible body 486. After the elongate flexible body 486 has been positioned such that the charger is aligned with the implanted medical device, the magnet 490 may be secured to the magnet 212 (or inductor magnet) to hold the charging appliance 482 in place. In other embodiments, the magnetic fastening arrangement may be replaced with a mechanical fastener such as a clip or a button.

Turning to FIG. 58, the exemplary scarf-like charging appliance 492 illustrated therein includes a charger 202 a and a scarf 494 that is configured to mount the charger in adjacent to the implanted medical device. The exemplary scarf 494 consists of an elongate flexible body 496, which has a pocket 498 with an opening 500 that is configured to receive the charger 202 a. Here, there is no fastening arrangement and the appliance 492 may be held in place by simply wrapping the scarf 494 around the neck as shown.

With respect to materials, suitable materials for the scarves 464, 484 and 494 include, but are not limited to, fleece, cotton, silk, Neoprene, polyester, and fabrics with moisture management aspects such as those sold under the trade name Dri-Lex (e.g. Dri-Lex 1230, Dri-Lex 2000 and Dri-Lex Fantasia). It should also be noted here that the scarves may be configured to place charger against higher on the neck than is shown in the Figures.

Chargers, charger mounting apparatus, and/or charging appliances may also be configured so as to allow the charger to be precisely and removably positioned in a variety of locations relative to the user's body. Referring first to FIGS. 59 and 60, the exemplary charging appliance 502 includes the charger 202 a, garment 504, and a mounting arrangement that is configured to mount the charger on the garment adjacent to the implanted medical device. In the illustrated embodiment, the garment 504 is a vest with flaps 506 and 508 and fasteners, such as a length of hook material 510 on the inner surface of one flap and a length of loop material 512 on the exterior surface of the other. The length of loop material 512 is wider than the length of hook material 510 in order to accommodate wearers of different size. Other fastening arrangements may also be employed. For example, the loop material 512 may be omitted and the exterior surface of the flap 508 may be formed from a hook compatible material (e.g. cotton or fleece). Other suitable fasteners include, but are not limited to, hooks, buttons, snaps, zippers and buckles. Moreover, in other implementations, a pullover type vest without openable flaps and fasteners may be employed.

Turning to the manner in which the charger is mounted on the garment in the exemplary charging appliance 502 illustrated in FIGS. 59 and 60, the charger 202 a and the garment 504 are provided with respective areas of hook material 514 and loop material 516. The garment 504 may be formed from any suitable garment-type material as well as from fabrics with moisture management aspects such as those sold under the trade name Dri-Lex (e.g. Dri-Lex 2000 and Dri-Lex Fantasia). Although the hook material 514 is positioned on the rear of the charger housing 206 in the illustrated embodiment, it may also be positioned on the front of the charger housing. The loop material 516 is located on the front shoulder and upper chest portion of the exterior each flap 506 and 508. The portions of the flaps 506 and 508 covered with (or formed by) the loop material 516 may be increased or decreased, and all or part of the back side of the garment may be covered with (or formed by) the loop material. Additionally, or alternatively, some or all of the inner surfaces of the garment may be covered with (or formed by) the loop material, as is the case of the exemplary garment 504 a illustrated in FIG. 61. Material such as cotton, fleece, unbroken loop Neoprene or other hook compatible material may also be substituted for the hook compatible loop material 516.

Another alternative is to employ a pouch that is configured to carry a charger and a mounting apparatus that is configured to secure to the pouch to the garment. One such pouch is the exemplary pouch 518 illustrated in FIGS. 62 and 63, which may mounted on a garment by way of loop material or other hook compatible material on a garment (e.g. loop material 516 on garment 504) and an area of hook material 520 on the pouch. With respect to the particular configuration of the pouch, the exemplary pouch 518 include a pocket 522 for the charger 202 a, a front aperture 524, and a flap 526. Other exemplary pouch configurations include, but are not limited to, those described above with reference to FIGS. 29A-29E.

It should also be noted that garments with hook material that functions in the manner illustrated in FIG. 59 are not limited to vests. Shirts, pants, and undergarments are other examples of garments which may include (or be at least partially formed by) loop or other fastener material in order to facilitate the mounting of a charger or charger pouch that includes corresponding hook or other fastener material. Moreover, the above-described shoulder and chest harnesses (FIGS. 30-45), shoulder drapes (FIGS. 47-50) and neck-related apparatus (FIGS. 51-58) may be reconfigured such that the charger pockets are eliminated and regions of these devices include, or are formed by, loop material or other hook compatible material to which the hook material on the charger illustrated in FIG. 60 and/or pouch illustrated in FIGS. 62 and 63 can be secured.

In other implementations, one or more inductors may be permanently secured to or within a wearable device, such as any of the wearable devices illustrated in or described in the context of FIGS. 3-17, 19 and 30-59, to form a charging appliance that includes the wearable device. For example, in the exemplary charging appliance 528 illustrated in FIGS. 64-66, an inductor apparatus 530 carries an inductor and inductor related circuitry (e.g. inductor 24 c and inductor related circuitry 25) and is permanently secured to the inner surface of the above-described knee brace 180. The inductor 24 c and inductor related circuitry 25 may be molded into an epoxy, silicone, or urethane structure that is carried within a plastic case 532. Alternatively, the inductor 24 c and inductor related circuitry 25 may be carried within a polycarbonate case, that is itself coated with an insulating encapsulate such as silicone, rubber-like polymers, Teflon, and other plastics. In either embodiment, the inductor apparatus 530 will be electrically insulated from the wearer and water resistant. Suitable devices for securing the inductor apparatus 530 to the cuff 182 or other portion of the knee brace 180 include adhesives and/or mechanical fasteners that are configured not to be released after they have been fastened.

The exemplary embodiment illustrated in FIGS. 64-66 includes a cable 106 a with a connector 534 that is configured to mate with a corresponding connector 536. So configured, the cable 106 a may be used to connect the power supply and control apparatus within remote housing 104 to, or disconnect the power supply and control apparatus from, the inductor 24 c and inductor related circuitry 25 in the inductor apparatus 530. In the embodiment illustrated in FIGS. 64-66, the cable 106 a is permanently secured to the housing 104. However, in other embodiments, the cable 106 a may be permanently secured to the inductor apparatus and the connector 534 used to connect the cable to the remote housing. Another alternative is to provide a cable with connectors at both ends.

Ear muffs are another example of a wearable device which may form part of a charging appliance and, to that end, the exemplary charging appliance 538 illustrated in FIGS. 67 and 68 includes the inductor apparatus 530 and ear muffs 540. The ear muffs 540 consist of a pair of ear pads 542 and a resilient head band 544 on which the ear pads are mounted. The inductor apparatus 530 is carried within one of the ear pads 542 and, to that end, the ear pad includes an aperture 546 to facilitate mating of the connectors 534 and 536. The power supply and control apparatus within the remote housing 104 may, therefore, be connected to and disconnected from the inductor apparatus 530 as desired.

Other exemplary charging appliances that include the remote housing 104, as well as the power supply and control apparatus therein, the inductor apparatus 530, and a wearable device are illustrated in FIGS. 69-80.

The necklace 578 may be the illustrated choker length, or longer, depending on the location of the implanted medical device.

In the exemplary charging appliance 584 illustrated in FIGS. 77 and 78, the inductor apparatus 530 is carried within an earring 586 that has an ear clip 588 and an aperture 590. Here too, the aperture allows the connectors 534 and 536 and, therefore, the power supply and control apparatus and the inductor, to be connected to one another.

Other types of jewelry to which an inductor apparatus may be secured include, but are not limited to piercings, wrist watches, headbands, bandanas, anklets, bracelets, pendants, and broaces.

As alluded to above in the context of the knee brace illustrated in FIGS. 64-66, an externally worn medical device is another example of a device that may be part of a charging appliance. Other exemplary charging appliances that include externally worn medical device are illustrated in FIGS. 79 and 80. Referring first to FIG. 79, the charging appliance 592 includes a thyroid guard 594 and the inductor apparatus 530. The inductor apparatus 530 may be secured to the neck portion of the thyroid guard (as shown) or to the portion that hangs downwardly from the neck portion. The remote housing and the power supply and control apparatus therein may be connected to the inductor apparatus 530 by the cable 106 a.

The inductor apparatus 530 may be glued or otherwise secured to the inner surface of the thyroid guard or neck brace (as shown), one the outer surface, or carried between the inner and outer surfaces.

Still other charging appliances include an inductor apparatus and a mounting device that is configured to adhere to the wearer's skin. Such mounting devices permit the an inductor to be positioned at essentially any location on the wearer's body. For example, the charging appliance 600 illustrated in FIGS. 81 and 82 includes an inductor apparatus 602 with an inductor and inductor related circuitry (e.g. inductor 24 c and inductor related circuitry 25), an adhesive strip 604, and a remote housing 104 b, with the above-described power supply and control apparatus and user interface. The remote housing 104 b may be connected to the inductor apparatus 602 in the manner described below.

The inductor and inductor related circuitry in the exemplary inductor apparatus 602 may be molded into an epoxy, silicone, or urethane structure that is carried within a plastic case. Alternatively, the inductor and inductor related circuitry may be carried within a polycarbonate case, that is itself coated with an insulating encapsulate such as silicone, rubber-like polymers, Teflon, and other plastics. In either embodiment, the inductor apparatus 602 will be electrically insulated from the wearer and water resistant. The inductor apparatus 602 is also provided with a cable 106 b that has a connector 606. The connector 606 is configured to mate with a corresponding connector 608 on the remote housing 104 b. In the exemplary embodiment, the cable 106 b is permanently secured to the inductor apparatus 602. However, in other embodiments, the cable 106 a may be permanently secured to the remote housing and a connector used to connect the cable to the inductor apparatus. Another alternative is to provide a cable with connectors at both ends.

The exemplary adhesive strip 604, which is similar to those commonly associated with conventional adhesive bandages, includes a backing 610 and a layer of adhesive 612. Suitable materials for the backing 610 include, but are not limited to, woven fabrics, plastics, and latex rubbers, while the adhesive may be a hypoallergenic adhesive that will adhere to the skin, yet exhibit enough release when intentionally removed so as not to tear the skin or leave a residue. The backing 610 may be pressed over the inductor apparatus 602 prior to the application of the adhesive so that the adhesive layer 612 covers the inductor apparatus as well as the backing, as shown in FIG. 82. Alternatively, as illustrated for example in FIG. 83, the adhesive layer 612 a may be applied to the backing 610 prior to the backing being pressed over the inductor apparatus 602. In either case, a release liner (not shown) may be placed over adhesive layer 612 (or 612 a) to facilitate storage.

Another charging appliance that is configured to adhere to the wearer's skin is generally represented by reference numeral 614 in FIGS. 84 and 85. Charging appliance 614 includes an inductor apparatus 616 with an inductor and inductor related circuitry (e.g. inductor 24 c and inductor related circuitry 25), an adhesive disk 618, and a remote housing 104, with the above-described power supply and control apparatus and user interface. The remote housing 104 may be connected to the inductor apparatus 616 in the manner described below.

The inductor and inductor related circuitry in the exemplary inductor apparatus 616 may be molded into an epoxy, silicone, or urethane structure that is carried within a plastic case. Alternatively, the inductor and inductor related circuitry may be carried within a polycarbonate case, that is itself coated with an insulating encapsulate such as silicone, rubber-like polymers, Teflon, and other plastics. In either embodiment, the inductor apparatus 616 will be electrically insulated from the wearer and water resistant. The inductor apparatus 616 is also provided with a connector 620 that extends through the adhesive disk 618. Suitable connectors include the types frequently found on conventional EKG electrodes. A cable 106 c, with a corresponding connector 622, may be used to connect the power supply and control apparatus within the remote housing 104 to, or disconnect the power supply and control apparatus from, the inductor and inductor related circuitry in the inductor apparatus 616. However, in other embodiments, the cable may be permanently secured to the inductor apparatus and a connector used to connect the cable to the remote housing. Another alternative is to provide a cable with connectors at both ends.

The exemplary adhesive disk 618, which is similar to those commonly associated with conventional EKG electrodes, includes a backing 624 and a layer of adhesive 626. Suitable materials for the backing 624 include, but are not limited to, woven fabrics, plastics, and latex rubbers, while the adhesive 626 may be a hypoallergenic adhesive that will adhere to the skin, yet exhibit enough release when intentionally removed so as not to tear the skin or leave a residue. The backing 624 may be pressed over the inductor apparatus 616 prior to the application of the adhesive so that the adhesive layer 626 covers the inductor apparatus as well as the backing (as shown). Alternatively, an adhesive layer may be applied to the backing 624 prior to the backing being pressed over the inductor apparatus 602. In either case, a release liner (not shown) may be placed over the adhesive layer to facilitate storage.

The exemplary charging appliance 628 illustrated in FIGS. 86 and 87 is also configured to adhere to the wearer's skin and, to that end, includes a suction cup 630 in addition to the inductor apparatus 616 and remote housing 104. The inductor apparatus 616, which is secured to the inner surface of the suction cup (e.g. with adhesive), is connected to the power supply and control apparatus associated with the remote housing 104 by the cable 106 c. To that end, the connector 620 extends through an otherwise sealed aperture (not shown) in the top portion of the suction cup 630 such that it may be connected to the connector 622 on cable 106 c.

Although the charging appliance is not limited to any particular suction cup, the exemplary suction cup 630 is circular in shape when viewed in plan, has a smooth circular sealing surface 632, and is formed from a flexible material such as rubber, PVC plastic or neoprene. The suction cup 630 is biased to the relaxed state illustrated in FIG. 86. When the suction cup 630 is pressed against the wearer's skin, air is forced out of the interior of the suction cup, a seal is created between the sealing surface 632 and the skin, and the vacuum created by the biasing force of the suction cup secures the cup to the skin, as is shown in FIG. 87. The respective sizes and shapes the inductor apparatus 616 and suction cup 630 result in the inductor apparatus being in close proximity to, or in contact with, the skin.

Other charging appliances include an inductor that extends around a portion of the body. One such charging appliance is generally represented by reference numeral 634 in FIGS. 88 and 89. The charging appliance 634 includes an inductor apparatus 636 and a remote housing 104, with the above-described power supply and control apparatus and user interface.

The exemplary clasp 640, which physically connects the free ends of the inductor portion 638, includes a first portion 646, a second portion 648 and a latch 650 that releasably secures the first and second portions to one another. The inductor related circuitry 25 is molded into the first clasp portion 646. A conductor line 652, which includes separable sections in the first and second clasp portions 646 and 648, electrically connects the free ends of the inductor coil 642 to the circuitry 25 when the clasp 640 is closed (as shown). The clasp 640 also includes a connector 654 that is configured to mate with a connector 656 on the cable 106 d, thereby connecting the inductor apparatus 636 to the power supply and control apparatus within the remote housing 104. In other embodiments, the cable 106 d may be permanently secured to the clasp 640 and a connector used to connect the cable to the remote housing, or a cable with connectors at both ends may be provided. In still other embodiments, where the loop formed by the inductor portion 638 is large enough to fit over the wearer's head, the clasp 640 may be replaced by an unopenable structure that otherwise performs the same functions as the clasp.

In the illustrated embodiment, the inductor apparatus 636 is a resilient structure and may be removed from the wearer's neck by unlatching the clasp 640, thereby allowing the first and second clasp portions 646 and 648 to be separated from one another, and pulling the free ends of the inductor portion 638 away from one another. To that end, suitable materials for the inductor coil 642 include, but are not limited to, copper, copper alloys, and silver, and suitable materials for the electrically insulating exterior portion 644 include, but are not limited to, plastics such as PVC that is the desired color or is painted the desired color. Suitable materials for the clasp 640 include, but are not limited to, plastics such as PVC. Alternatively, the exterior portion 644 may be partially covered by a decorative element formed from gold or other suitable metals and non-metals, as is described below with reference to FIG. 93. The configuration of clasp 640 and exterior portion 644 should also be such that the charging appliance is waterproof (or at least water resistant).

It should also be noted that, although inductor coil 642 is in the form of a singe loop in the illustrated embodiment, other embodiments may include a plurality of loops within the electrically insulating exterior portion 644 and a connector similar to that described below with reference to FIG. 91.

Another charging appliance which includes an inductor that extends around the associated portion of the body is generally represented by reference numeral 658 in FIGS. 91 and 92. The charging appliance 634 includes an inductor apparatus 660 and a remote housing 104, with the above-described power supply and control apparatus and user interface. The remote housing 104 may be connected to the inductor apparatus 660 in the manner described below.

The exemplary inductor apparatus 660, which is configured to look like a multiple ring necklace, includes a plurality of rings 662 a-d, a clasp 664, and an inductor coil 666 that passes through the rings and clasp. The clasp 664 has first and second portions 668 and 670 and a latch 672. Each of the rings 662 a-d has a pair of free ends that are in close proximity to one another and respectively secured to the clasp portions 668 and 670. The clasp 664 is also provided with a connector 674 that is configured to mate with a connector 656 on a cable 106 e, thereby connecting the inductor apparatus 660 to the power supply and control apparatus within the remote housing 104. The cable 106 e also includes a housing 675 that carries the inductor related circuitry 25. In other embodiments, the cable 106 e may be permanently secured to the clasp 664 and a connector used to connect the cable to the remote housing, or a cable with connectors at both ends may be provided. Also, the inductor related circuitry 25 may be carried within the clasp 664 and the housing 275 may be omitted.

The illustrated inductor coil 666 includes a first free end that is associated with one of the free ends of ring 662 a and is connected to the connector 674. The inductor coil 666 also extends through ring 662 a to the other free end thereof, though the clasp 664 to one of the free ends of ring 662 b, through ring 662 b to the other free end thereof, though the clasp to one of the free ends of ring 662 c, through ring 662 c to the other free end thereof, though the clasp to one of the free ends of ring 662 d, and through ring 662 d to the other free end thereof. The free end of the inductor coil 666 associated with ring 666 d is connected to the connector 674. In order to accommodate passage through the separable clasp 664, the inductor coil 666 has three discontinuities. The portions of the inductor coil 666 on opposite sides of each discontinuity are connected to one another when the clasp 664 is closed, and disconnected when the clasp is open.

Turning to FIG. 93, the exemplary rings 662 a-d include an insulating main portion 676, though which the inductor coil 666 passes, and a decorative portion 678 that is on the exterior side of the main portion that will be visible when the inductor apparatus 660 is worn. The inductor apparatus 660 is also resilient so that it can be spread apart when being put on and taken off. As such, suitable materials for the inductor coil 666 include, but are not limited to, metals such as copper, copper alloys, and silver, suitable materials for the main portion 676 include, but are not limited to, plastics such as PVC, and suitable materials for the decorative portion 678 include, but are not limited to gold, silver, other metals and decorative non-metals. Also, the configuration of clasp 664 and main portion 676 should also be such that the charging appliance is waterproof (or at least water resistant).

In one alternative implementation, the rings 662 a-d may be formed by a flexible, continuous coil-like structure that forms a plurality of loops and can be stretched to fit over the wearer's head. Here, the clasp will simply connect the free ends of the inductor coil within the coil-like structure to a connector (e.g. the connector 674). In other alternative implementations, which may include multiple rings or a single coil-like structure, the decorative portion may be omitted and the main portion 676 formed from a plastic that is (or is painted) the desired color.

The exemplary charging appliance 680 illustrated in FIG. 94, which also includes an inductor that extends around the associated portion of the body, includes an inductor apparatus 682 and a remote housing 104, with the above-described power supply and control apparatus and user interface. The exemplary inductor apparatus 682 is also configured to look like a necklace and includes a flexible band 684, a clasp 686, and an inductor coil 688 embedded within the flexible band. The inductor related circuitry 25 and a connector 654, which mates with the connector 656 on cable 106 d to connect the inductor apparatus 682 to the power supply and control apparatus within the remote housing 104, are also embedded within the flexible band 684. In other embodiments, the cable 106 d may be permanently secured to the free ends of the coil 688 a connector used to connect the cable to the remote housing. Another alternative is to provide a cable with connectors at both ends.

In the illustrated embodiment, the clasp 686 has first and second portions 690 and 692 and a latch 694. The inductor coil 688 passes through the clasp 686 and, to that end, has a pair discontinuities. The portions of the inductor coil 688 on opposite sides of each discontinuity are connected to one another when the clasp 686 is closed, and disconnected when the clasp is open.

With respect to materials, suitable materials for the flexible band include, but are not limited to, rubber, silicone and fabric (with insulating material over the inductor coil 688 in a manner similar to that shown FIG. 90), while suitable materials for the inductor coil 688 include, but are not limited to copper, copper alloys, silver and other suitable metals.

It should also be noted that although the exemplary charging appliances in the embodiments illustrated in FIGS. 88-94 include inductors that extend around the wearer's neck, inductors that are configured to extend around other body structures may also be employed. Such charging appliances may, for example, include inductor apparatus that look like bracelets, belts, upper arm spirals, and other devices that extend (along with the inductor) around the perimeter of a bodily structure.

There is a wide variety of other charging appliances which include a wearable device that serves a purpose other than positioning an inductor (or charger) on the wearer's body. One such wearable device is an eyeglass frame and, to that end, the exemplary charging appliance 696 illustrated in FIG. 95 includes sunglasses 698 in addition to the inductor 24 a, inductor related circuitry 25 and remote housing 104 (with the power supply and control apparatus and user interface). The sunglasses 698 consist of a frame 700, with a frame front 702 and a pair of arms 704, and lenses 706. A connector 536 is mounted on one of the arms 704 and the remote housing 104 may be connected to the inductor 24 a and inductor related circuitry 25 by the connector 534 on cable 106 a.

In the illustrated embodiment, the inductor 24 a is carried within the frame front 702 and the charging of an implanted medical device, such as an implanted occipital nerve stimulator, would typically occur when the sunglasses 698 are being worn backwards. Alternatively, or in addition, an inductor may be carried within one or both of the arms 704. The frame 700 may be formed from materials such as plastics, ceramics and non-conducting metals to insulate the wearer from the inductor 24 a and inductor related circuitry 25.

Another example of a charging appliance which includes a wearable device that serves a purpose other than positioning an inductor (or charger) on the wearer's body is the charging appliance generally represented by reference numeral 708 in FIGS. 96 and 97. Here, an inductor 24 c is incorporated into a personal cooler 710 that is worn on the neck and is suitably insulated from the wearer by, for example, a relatively soft plastic such as polyurethane. Although such charging appliances are not limited to any particular type of personal cooler, one example of such a personal cooler is the Personal Cooling System 3.0 sold by The Sharper Image. The personal cooler 710 includes a housing 712, an aluminum inner cooling surface 714, pads 716, a power supply 718, a controller 720, and a user interface 722.

The power supply and control functionality associated with the inductor 24 c in the exemplary charging appliance 708 may be performed by the personal cooler power supply 718 and controller 720 (as shown). Alternatively, a separate power supply and controller arrangement may be provided. The inductor related circuitry 25 may be positioned adjacent to the inductor 24 c within the housing 712 (as shown), or may be eliminated and the functionality thereof added to the controller 720.

Turning to FIG. 98, the exemplary charging appliance 724 is configured such that all of its components may be mounted on the same portion of the wearer's body. More specifically, the charging appliance 724 includes a harness 726, an inductor 24 c embedded within the harness and insulated from the wearer by, for example, a relatively soft plastic such as polyurethane, and a housing 104 c mounted on the exterior of the harness. The exemplary harness 726 consists of a relatively narrow strap 728 with an enlarged portion 730 that carries the inductor 24 c. The ends of the strap 728 may be secured to one another with any suitable fastener arrangement and, in the illustrated embodiment, hook and loop fastener strips 732 and 734 are employed. Suitable material for the harness 726 includes, but is not limited to, elastomeric material such as that sold under the trade name Neoprene. The elastomeric material may be covered with fabric to increase wearer comfort. The housing 104 c carries the power supply and control apparatus and inductor related circuitry as well as the user interface (e.g. a button 736).

The exemplary charging appliance 724 is sized and shaped so as to be positioned on the wearer's neck. Such positioning is suitable for charging an implanted occipital nerve stimulator. Other implementations may be sized and shaped for positioning around one of the wearer's arms or legs, or the waist or the chest.

The exemplary charging appliance 738 illustrated in FIG. 99 is essentially identical to that illustrated in FIG. 98 and similar elements are represented by similar reference numerals. Here, however, the charging appliance includes coil 24 b and the enlarged portion 730 a of the strap is configured therefore. Like charging appliance 724, charging appliance 738 may be sized and shaped for placement around the neck, arm, leg, waist or chest.

Turning to FIG. 100, exemplary charging appliance 740 is configured to position one or more inductors behind the wearer's neck. To that end, the exemplary charging appliance 740 includes an inductor apparatus 742 that is configured to be secured to the wearer's hair and a remote housing 104 with the above-described power supply and control apparatus and user interface.

The exemplary inductor apparatus 742 carries a pair of inductors 24 c and inductor related circuitry 25. The inductors 24 c and inductor related circuitry 25 may be molded into an epoxy, silicone, or urethane structure that is carried within a plastic housing 744. Alternatively, the inductors 24 c and inductor related circuitry 25 may be carried within a polycarbonate housing, that is itself coated with an insulating encapsulate such as silicone, rubber-like polymers, Teflon, and other plastics. In either embodiment, the inductor apparatus 742 will be electrically insulated from the wearer and water resistant. The inductor apparatus 742 also includes a band 746 which performs the function of securing the housing 744 to the wearer's hair. The housing 744 may be provided in a variety of colors in order to allow the housing color to be matched to the wearer's hair color.

The housing 744 and band 746 may be secured to one another in a variety of ways. For example, each end of the band may be releasably secured to the housing by an appropriate fastener. In the illustrated embodiment, one end of the band 746 is secured to a spring biased reel 748 that is carried within the housing 744 and applies a tension force to the band. A lumen 750, which extends from the exterior of the housing to the reel 748, allows portions of the band 746 to move in and out of the housing 744. A dull needle 752, which facilitates threading of the band through the wearer's hair, may be secured to the other end of the band 746. The dull needle 752 also includes a latch element 754 that is configured to mate with a latch 756 within the housing. A lumen 758 allows the dull needle 752 to be inserted into the housing 744 and the latch 756 secures the dull needle to the housing 744 when the dull needle reaches the latch. A latch release button 760, which disconnects the latch element 754 from the latch 756 when pressed to allow the dull needle 752 to be pulled out of the lumen 758, is also provided.

With respect to the configuration of the band 746, the band may be formed from any suitable flexible material or combination thereof. The band 746 may be circular in cross-section (as shown), flat, or any other cross-sectional shape. In addition, the band 746 may be configured, e.g. through the use of a high friction material such as silicone rubber or a textured outer surface, to prevent slippage relative to the wearer's hair. The band 746 may also be provided in a variety of colors in order to allow the band color to be matched to the wearer's hair color.

In other implementations, the spring biased reel 748 may be replaced with a reel that has a handle which may be turned to reduce the exposed length of the band 746, a ratchet which maintains the band at the desired exposed length, and a ratchet release button which allows the exposed length of the band to be increased. The reel may also be omitted. Here, the length of the band 746 will be fixed. Regardless of the type of reel, or lack thereof, the other end of the band 746 may be releasably secured to the housing through the used of a twist lock arrangement instead of the above-described latch element 754, latch 756 and release button 760. The end of the band 746 opposite the reel may also be permanently secured to the housing. Here, the dull needle 752 may be omitted and, instead of threading the band 746 through the hair, the band 746 will simply be worn like a conventional hair band or sweat band.

The housing 104, as well as the power supply and control apparatus carried therein, are permanently connected to the inductor apparatus 742 by the cable 106 in the illustrated implementation. In other implementations, the cable may be permanently secured to one of the housing 104 and inductor apparatus 742 and releasable connected to the other by an appropriate connector arrangement, or releasable secured to both through the use of a cable with connectors at both ends.

It should also be noted here that inductors and inductor apparatus may be carried by and/or incorporated into a wide variety of wearable devices in addition those described above with reference to FIGS. 3-100. By way of example, but not limitation, such wearable devices include priest collars, fetal monitors, scuba suits, suspenders, body piercings, body tissue screws, head bands, splints, and gel pads.
